A blinking red light on a Tesla Wall Connector means it has detected a fault and stopped charging. Tesla’s documentation uses the number of red flashes to indicate the type of fault, such as a ground fault, over-temperature, a wiring or supply problem, or an internal error. Count the flashes, check Tesla’s troubleshooting guide for your model, and try the basic steps below.
Common Causes
| Cause | What to check |
|---|---|
| Ground fault | Moisture in connector or car inlet, cable damage |
| Over-temperature | Sun on the unit, hot terminals, high ambient temperature |
| Supply or wiring | Breaker, loose connection, wrong configuration |
| Communication | Connector not fully seated; vehicle fault |
| Internal | Contact Tesla |
Safe Steps
- Unplug from the car and reconnect firmly.
- Switch off the breaker for about 30 seconds, then on.
- Inspect the connector, cable and inlet for water, debris or damage.
- Try another vehicle or charger to see which side has the fault.
- If it repeats, stop and contact an electrician or Tesla.
Other Lights
Green typically indicates ready or charging, and blue relates to connectivity or communication; see Tesla’s guide for exact meanings. For any brand, see why is my EV charger flashing red. EVDANCE chargers such as the EVDANCE EV-ACS4005T 40A NACS portable charger show faults as text on a colour screen.
